Just a day after an omnibus release spanning all of Apple's operating systems, the company has released beta versions of macOS Sierra 10.12.5, iOS 10.3.2, tvOS 10.2.1, and watchOS 3.2.2 to developers.

No significant release notes accompany the new beta software releases. Given that they aren't full "point" updates, they likely contain only bug fixes and minor revisions to problems introduced with Monday's more major revisions.

The only insight so far on the new Sierra version from Apple is that it "improves the stability, compatibility, and security of your Mac."

As with all the previous betas, the tvOS beta must be installed through a USB-C cable connecting the device to iTunes. The watchOS beta is installed with the watch on the charger, and in range of the paired iPhone.

Registered iOS devices can acquire the beta through the regular upgrade process, or through iTunes. The new Sierra beta can be downloaded as an image through the Apple Developer Center or through Software Update.

It is not clear why iOS and WatchOS have skipped an increment.

The macOS Sierra 10.12.5 beta has build number 16F43c, with iOS 10.3.2 sporting 14F5065b. The tvOS 10.2.1 and watchOS 3.2.2 betas have build number 14W5563b and 14V5465b, respectively.
